Growing a Forest Rapidly

1. First, you start with soil. We identify what nutrition the soil lacks. 2. Then we identify what species we should be growing in this soil, depending on climate. 3. We then identify locally abundant biomass available in that region to give the soil whatever nourishment it needs. This is typically an agricultural or industrial byproduct — like chicken manure or press mud, a byproduct of sugar production — but it can be almost anything. We’ve made a rule that it must come from...

 Astrochicken

The basic idea of Astrochicken is that the spacecraft will be small and quick. I do not believe that a fruitful future for space science lies along the path we are now following, with space missions growing larger and larger and fewer and fewer and slower and slower as the decades go by. I propose a radical step in the direction of smallness and quickness. Astrochicken will weigh a kilogram instead of Voyager's ton, and it will travel from Earth into orbit around Uranus in two years instead ...
